Abstract

Processed low carbon iron metal and process and apparatus for its production, using high water-vapordecarburization, are provided. The iron metal product is characterized by fine grain structure with average carbon content less than about 0.04%. The process is carried out using a cost beneficial protocol including the step of processing scrap steel segments at high density in a strongly decarburizing atmosphere.
